Question

我是学习C＃的新手并且有一个问题。我有一个带有测试和分数的txt文件，如下所示

ACT
21.0
SAT
478.9
CLEP
69.1
ACT 32.0

如何将此txt解析为字典并显示如下（删除任何重复项）

ACT 21.0
SAT 478.9
CLEP 69.1

以下是我的尝试

namespace Generate
{
    class generateInputStream
    {
        static void Main(string[] args)
        {
            FileManager objfileManager = new FileManager();
            FileStream fs = null;

            Console.Write("Enter the file path: ");

            while (fs == null)
            {
                string Path = Console.ReadLine();
                fs = objfileManager.OpenFile(Path);
            }
            int 

        }

    }

    public class FileManager
    {
        public FileStream OpenFile(string Path)
        {
            try
            {
                return new FileStream(Path, FileMode.Open, FileAccess.Read);
            }

            catch (Exception e)
            {
                Console.Write("Problem opening file {0}, please enter a valid path: ", Path);
            }
            return null;
        }

         public List<string> ReadLines(FileStream File)
        {
            List<string> text = new List<string>();
            try
            {
                var streamReader = new StreamReader(File);

            }
            catch (Exception e)
            {
                Console.Write(e.Message);
            }
            return text;
        }

        static readFileIntoDictionary()
        {
            StreamReader generateInputStream;
            var  streamReader  = new StreamReader();

            SortedDictionary<string, double> dic = new SortedDictionary<string, double>();

            string Key = string.Empty;
            double Value = 0.0;


            while ((Key = streamReader.ReadLine())!= null) 
            {
               Value = Convert.ToInt32(streamReader.ReadLine());

                dic.Add(Key, Value);   
            }
            streamReader.Close();

            return dic;
        }

        static displayScoreData()
        {
            readFileIntoDictionary(); 
           foreach (KeyValuePair<string, double> pair in dic)
            {
                Console.WriteLine(pair.Key, "-",pair.Value);
               }
        }
    }
}

这种方法应该对你有所帮助。这里没有错误处理，因此我们假设您的文件格式正确。

public static KeyValuePair<string, decimal>? ReadPair (StreamReader sr)
{
    if (sr.EndOfStream) return null;

    string  key   = sr.ReadLine ();
    decimal value = decimal.Parse (sr.ReadLine ());

    return new KeyValuePair<string, decimal> (key, value);
}

我不知道什么是重复的，同样的密钥？相同的键+值？

C＃重复<k，v =“”>
